Thanks for the entries! I'm glad to see two different concepts, rather than a couple versions of the same one.
One overall comment I have is that Swim and Tennis Club is minimized in both logos - I'd like to seem them slightly more pronounced. Also, the delineation between the wave and the tennis ball in entry 11 is stronger than I'd like to see - I wonder if you have ideas for making this more subtle or slightly rougher looking.
I do like the intent behind Entry 12, but I don't think people in my club will get it - they will mostly see figures which bring to mind children and the heart symbol. Would it be possible to add a racket or swimsuit or diving board to make the parent/child characters activity explicitly swim & tennis?
